"The remote Windows host is missing security update 4103721.
It is, therefore, affected by multiple vulnerabilities :

  - A security feature bypass vulnerability exists in .Net
    Framework which could allow an attacker to bypass Device
    Guard. An attacker who successfully exploited this
    vulnerability could circumvent a User Mode Code
    Integrity (UMCI) policy on the machine.  (CVE-2018-1039)

  - A remote code execution vulnerability exists in the way
    that Microsoft browsers access objects in memory. The
    vulnerability could corrupt memory in a way that could
    allow an attacker to execute arbitrary code in the
    context of the current user. An attacker who
    successfully exploited the vulnerability could gain the
    same user rights as the current user.  (CVE-2018-8178)

  - A remote code execution vulnerability exists in
    Microsoft COM for Windows when it fails to
    properly handle serialized objects. An attacker who
    successfully exploited the vulnerability could use a
    specially crafted file or script to perform actions. In
    an email attack scenario, an attacker could exploit the
    vulnerability by sending the specially crafted file to
    the user and convincing the user to open the file.
    (CVE-2018-0824)

  - A remote code execution vulnerability exists when
    Windows Hyper-V on a host server fails to properly
    validate vSMB packet data. An attacker who successfully
    exploited these vulnerabilities could execute arbitrary
    code on a target operating system. To exploit these
    vulnerabilities, an attacker running inside a virtual
    machine could run a specially crafted application that
    could cause the Hyper-V host operating system to execute
    arbitrary code. The update addresses the vulnerabilities
    by correcting how Windows Hyper-V validates vSMB packet
    data. (CVE-2018-0961)

  - An information disclosure vulnerability exists when
    affected Microsoft browsers improperly handle objects in
    memory. An attacker who successfully exploited this
    vulnerability could obtain information to further
    compromise the users system.  (CVE-2018-1025)

  - A remote code execution vulnerability exists in the way
    that the scripting engine handles objects in memory in
    Internet Explorer. The vulnerability could corrupt
    memory in such a way that an attacker could execute
    arbitrary code in the context of the current user. An
    attacker who successfully exploited the vulnerability
    could gain the same user rights as the current user.
    (CVE-2018-0955, CVE-2018-8114, CVE-2018-8122)

  - An elevation of privilege vulnerability exists when the
    Windows Common Log File System (CLFS) driver improperly
    handles objects in memory. An attacker who successfully
    exploited this vulnerability could run processes in an
    elevated context.  (CVE-2018-8167)

  - A security feature bypass vulnerability exists in
    Windows which could allow an attacker to bypass Device
    Guard. An attacker who successfully exploited this
    vulnerability could circumvent a User Mode Code
    Integrity (UMCI) policy on the machine.  (CVE-2018-0958,
    CVE-2018-8129, CVE-2018-8132)

  - An information disclosure vulnerability exists when the
    Windows kernel improperly handles objects in memory. An
    attacker who successfully exploited this vulnerability
    could obtain information to further compromise the users
    system.  (CVE-2018-8127)

  - A remote code execution vulnerability exists in the way
    that the VBScript engine handles objects in memory. The
    vulnerability could corrupt memory in such a way that an
    attacker could execute arbitrary code in the context of
    the current user. An attacker who successfully exploited
    the vulnerability could gain the same user rights as the
    current user.  (CVE-2018-8174)

  - A remote code execution vulnerability exists in the way
    that the Chakra scripting engine handles objects in
    memory in Microsoft Edge. The vulnerability could
    corrupt memory in such a way that an attacker could
    execute arbitrary code in the context of the current
    user. An attacker who successfully exploited the
    vulnerability could gain the same user rights as the
    current user.  (CVE-2018-0943, CVE-2018-8130,
    CVE-2018-8133)

  - A security feature bypass vulnerability exists when
    Microsoft Edge improperly handles requests of different
    origins. The vulnerability allows Microsoft Edge to
    bypass Same-Origin Policy (SOP) restrictions, and to
    allow requests that should otherwise be ignored. An
    attacker who successfully exploited the vulnerability
    could force the browser to send data that would
    otherwise be restricted.  (CVE-2018-8112)

  - A denial of service vulnerability exists when .NET and
    .NET Core improperly process XML documents. An attacker
    who successfully exploited this vulnerability could
    cause a denial of service against a .NET application. A
    remote unauthenticated attacker could exploit this
    vulnerability by issuing specially crafted requests to a
    .NET (or .NET core) application. The update addresses
    the vulnerability by correcting how .NET and .NET Core
    applications handle XML document processing.
    (CVE-2018-0765)

  - An elevation of privilege vulnerability exists when the
    Windows kernel fails to properly handle objects in
    memory. An attacker who successfully exploited this
    vulnerability could run arbitrary code in kernel mode.
    An attacker could then install programs; view, change,
    or delete data; or create new accounts with full user
    rights.  (CVE-2018-8897)

  - An information disclosure vulnerability exists when
    Chakra improperly discloses the contents of its memory,
    which could provide an attacker with information to
    further compromise the users computer or data.
    (CVE-2018-8145)

  - An elevation of privilege vulnerability exists when the
    DirectX Graphics Kernel (DXGKRNL) driver improperly
    handles objects in memory. An attacker who successfully
    exploited this vulnerability could run processes in an
    elevated context.  (CVE-2018-8165)

  - A remote code execution vulnerability exists in the way
    that Windows handles objects in memory. An attacker who
    successfully exploited the vulnerability could execute
    arbitrary code with elevated permissions on a target
    system.  (CVE-2018-8136)

  - A remote code execution vulnerability exists when
    Windows Hyper-V on a host server fails to properly
    validate input from an authenticated user on a guest
    operating system.  (CVE-2018-0959)

  - An elevation of privilege vulnerability exists in
    Windows when the Win32k component fails to properly
    handle objects in memory. An attacker who successfully
    exploited this vulnerability could run arbitrary code in
    kernel mode. An attacker could then install programs;
    view, change, or delete data; or create new accounts
    with full user rights.  (CVE-2018-8124, CVE-2018-8164,
    CVE-2018-8166)

  - A security feature bypass vulnerability exists when
    Internet Explorer fails to validate User Mode Code
    Integrity (UMCI) policies. The vulnerability could allow
    an attacker to bypass Device Guard UMCI policies.
    (CVE-2018-8126)

  - An elevation of privilege vulnerability exists in the
    way that the Windows Kernel API enforces permissions. An
    attacker who successfully exploited the vulnerability
    could impersonate processes, interject cross-process
    communication, or interrupt system functionality.
    (CVE-2018-8134)

  - A remote code execution vulnerability exists in the way
    the scripting engine handles objects in memory in
    Microsoft browsers. The vulnerability could corrupt
    memory in such a way that an attacker could execute
    arbitrary code in the context of the current user. An
    attacker who successfully exploited the vulnerability
    could gain the same user rights as the current user.
    (CVE-2018-0954, CVE-2018-1022)

  - A remote code execution vulnerability exists when
    Microsoft Edge improperly accesses objects in memory.
    The vulnerability could corrupt memory in such a way
    that enables an attacker to execute arbitrary code in
    the context of the current user. An attacker who
    successfully exploited the vulnerability could gain the
    same user rights as the current user.  (CVE-2018-8179)

  - A remote code execution vulnerability exists in the way
    that the scripting engine handles objects in memory in
    Microsoft Edge. The vulnerability could corrupt memory
    in such a way that an attacker could execute arbitrary
    code in the context of the current user. An attacker who
    successfully exploited the vulnerability could gain the
    same user rights as the current user.  (CVE-2018-0945,
